Chosen Solution
Ok, so I cleaned it all out and put it all back together exactly as it was taken apart and it all works great untill about an hour after playing (Dead By Daylight), it just shuts down with no warning. I’m almost certain that it’s the system overheating, as I get the thermal throttling in game. But when I play a more relaxed game (like Rocket League) it runs just fine and stays nice and cool for the most part. What can I do to solve this issue? I’m leaning towards hardwiring the fan to the PSU by bridging the 5v brown wire of the fan to the 12v prong on the motherboard. Would that work?
I’d say check your fan cable first before doing the hard wiring. The cable or the fan itself might be damaged.
I would just suggest to wait and get a new fan than to hardwiring. Seems like the fan is failing because the ps4 sends control signals to the fan through one of the fan’s three wires for specific speed. If the ps4 is sending max fan speed signal and the fan is not turning at that much then the fan is faulty. Try taking the consoles top off and observing the fan patterns respective to game load and resting modes. Also alternative to hardwiring (little bit more tedious but could be fun) probably just take the fans wires and connect to a battery if that may not work due to no control signals then you may need to hook up an Arduino to send control signals to it and control the fan.
